DELBERT H. BONNELL, 0F OAKLAND, AND ALVA R. BOUK, OF SANTA RUSA, CALIFORNIA.

HYDRocAnBoN-BURNER.

Application filed April 25, 191'?.

To all whom t may concern.'

Be `it known that we, DEIBERT H. BON- NELL and ALVA R. Bonn, citizens of the United States, 'residing at Oakland and Santa Rosa, respectively, in the counties of Alameda and Sonoma, respectively, and State of California, have invented certain new and useful Im rovements in Hydrocarbon-Burners, of w iich the following is a specification.

This invention relates to improvements in hydrocarbon burners, more particularly to a burner adapted for the use of liquid fuel such as gasolene and distillate.

The principal object of our invention 1ste provide a device for the above purpose which is simple in construction, which contains no moving parts and which will efficiently vaporize and burn the fuels for which it is adapted.

With these and other objects in view the invention consists of certain novel features of construction, combinations and arrangements of parts hereinafter described and more specifically pointed out in the appended claims; it being understood that changes in form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit of the invention or sacriicing any of the advantages thereof.

Referring to the accompanying drawing forming a part of this speciication;

Figure 1 is a view in elevation of our improved burner.

Fig. 2 is a vertical section through the same.

Fig. 3 is a view partly in plan and partly in section.

Fig. 4 is a sectional view on the line 4 4, Fig. 2.

Fig. 5 is an enlarged view in section through the nozzle tip.

Referring to corresponding parts of the several views by the same numerals of reference, 1 denotes a hollow conical burner head having the cylindrical portion 2 formed on the upper end thereof. At the base of the latter where it joins the conical portion 1, is provided an annular rib 3 containing a concentric cavity 1 through which the liquid fuel may circulate.

At one side the rib 3 is provided with an inlet opening 5 to which is attached the feed pipe 6 leading from a tank or other source of Specification of Letters Patent.

feed supply (not shown). The cavity 4t is substantially filled with a wire screen 8 of line mesh which is folded in a zigzag manner and forced into the cavity through the inlet opening. This screen serves a twofold purpose; to prevent the entrance of dirt into the burner tip and to transmit heat to the liquid and gaseous vapors which may pass through the said cavity.

Spa-ced about ninety degrees from the inlet opening are two lugs 12 in which are bars 17 by which the burner is held in position.

On the apex of the conical portion 1 is formed an extension 7 which has a cavity that is connected by a passage-way 9 with the cavity 4 at a point diametrically opposite the inlet opening. This passage is formed in the wall of the conical portion 1 as shown in Fig. A. The upper endcf the cavity in extension 7 is screw-threaded as shown at 10 for the reception of the burner tip 11, which is provided with a hexagonal head 13 by which it may be screwed into position. Extending axially through this tip is a small discharge orifice 14: which at its lower end opens into the tapered recess 15 that forms a seat for the regulating needle 16. The latter is formed on the upper end of the screwthreaded portion 16 which engages a correspondingly threaded portion within the stein 7. A stem 19 extends from the lower end of 16 through a suitable packing gland 18 and is provided with a handle 20 or other means.

for turning the same.

The outside of the extension 7 is screwthreaded and engaged thereon is a circular dish-shaped member 21 having a cavity therein opening upwardly to provide a recess in which a priming liquid may be placed when the burner is being started.

Adjacent the apex of the head is a plurality of rows of holes denoted by 22 and adjacent the top of this head, just under the rib 3 is another row of holes denoted by 23.

The portion 2 extends upwardly from the rib 3 and seated thereon is a cylindrical sleeve 24 containing a number of air holes 26 circumferentially arranged as shown in Fig. 1.

The operation is as follows To start, the rib 3 is heated by igniting an easily vaporized fuel in the pan 21 and then the regular fuel is admitted to the cavity 4 through the pipe 6. When this fuel comes into contact with the heated walls of the cavity and the line wire screen it is vaporized and cracked so that only gas flows down the passageway 9 and issues from the orifice 14. Considerable pressure is maintained on the liquid fuel so that the gas issuing from the orifice 14: has a high velocity and draws air through the openings 22 and 23 to secure the necessary oxygen for combustion. Additional air is drawn through the openings 26 so that the flame fills the whole sleeve and depending` on the adjustment, extends beyond the outer end of the same.

le claim as new and wish to cover by Letters Patent l. A hydrocarbon fuel burner comprising a hollow conical body portion, a nozzle having a discharge orifice positioned in the apex of said hollow body, a circumferential rib around the large end of said body portion, said rib having a concentric cavity, a fine mesh wire screen having a plurality of folds disposed transversely of said cavity and said body portion having a passageway connecting the cavity of said rib with the orifice in said nozzle.

2. A burner for hydrocarbon fuels comprising a body portion having a conical recess, a nozzle having a discharge orifice in the apex of said recess, and a rib formed on said body portion, said rib and said body portion having a liquid passageway communicating with said discharge orifice, a plurality of folds of ne mesh screen disposed transversely of said liquid passage way.

3. A burner for hydrocarbon fuels comprising a body portion having an open ended conical recess, a nozzle having a discharge orifice positioned in the apex of said recess, said body having a closed fuel vaporizing cavity communicating with said orifice and a plurality of wire screen sections disposed transversely of said cavity.

In testimony whereof we aflix our signatures.
